pplication flled J'uly 19,

T all 'who'm 'it may concem:

Be it known that I, WILLIAM Gr. WILsoN, a citizen of the United States,residing at West New Brighton, in the county of Richmond and State ofNew York, have invented new and useful Improvements in Hose Couplings,of which thefollowing is a specication.

This invention relates to hose' couplings and theprincipal object is toprovide a device of this nature with a gasket so formed and positionedas to expand under the pressure of the water to form a tight Seal andwithout cracking said gasket.

Another object is to providea device of this nature which, shall besimple of" con- Struction, cheap to manufacture, and highly eflicientfor the purpose for which it is designed.

. With these and'other objects in view which .will bemo-re apparent atthe specification proceeds, the invention resides in certain novelconstruction and combination and ar-` ran ement of parts, the essentialfeatures of whicli'are hereinaft'er fully described, are particularlypointed out in the appended claim and are illustrated in theaccompanyindrawing', in whi`c`h:- w igure 1 is a side elevation of myimproved hose coupling.

F igure 2 is a longitudinal section of the same.

Figure 3 is a. fra entary detail of the flange end of the swivel memberbefore beini4 expanded. i

` `igure 4 is a fragmentary enlargedsectional view illustrating thegasket construction. Like characters of reference refer to like parts inall'viewsi Referring to the .drawing in detail, 10 l and 11 representthe end portions of .the coupling, and 12 represents the intermediateportionthereof which is swiveled on the member 10 and threadedly engagesmember 11 as will now'be described. Members 1911. serial No. 485,798.

10 and 11 are provided with threads at 13 and 14 for attachment to hoseSections, as,

is usual.

The member 11 is provided with a reduced and threaded portion 15 whichengag'es with an internally threaded portion 16 of member 12 and abutsagainst a gask'et 17 to effect a seal between members 11 and 12.

Member 10 is formed with a sleeve-'like inner end 18 terminat-ing in afiange 19 which is expanded into a seat or annular groove 20 in member12 so that' members 10 and 12 are swiveled together. Mating annulargrooves 21 and 22. are cut in the co-active faces of the members 10 and12 and seated in this ho-using formed by grooves 21 and 22 is a rubbergasket 28 faced on its sides by brass washers 24. rPhe brass' washersre- |ceive the wear of the yparts due to the rotation of member 12 onmember 10, and are i struck out in tangs 25 which sink into 'and lgripgasket 23. Gasket 23 is formed in substantially U-shaped' cross-sectionso that when the water is forced against the inner surface, the legswill expand to efi'ect a tight seal, and there will not be the tendencyto split the asket that there would be if the gasket ha 'an ang'ularinner Outline.

What is claimed as new is The comblnatlon of-a palr of members,

each provided with a portion for engage- I ment'with a hose section, anintermediate member 'swivelled to one of said members andl threadedlyengagifing` the other of said members, a gasket of U-s'hapedcross-section interposed between saidv intermediate member and that oneof said pair of members to 'which said intermediatemember 1s swivelled,and metal facing on opposite sides of said gasket an'df7 secured theretoby tangs struck out from said metal fac- 1n s. t

n testimony whereof I have affixed my signature.

WILLIAM G. WILSON.
